Answer 3

Light sleep, decreased breathing, hypnagogic sensation, hallucinations

NREM 1 includes slowed breathing and hypnagogic sensations.

Question 4

What are sleep spindles?

Answer 4

Bursts of rapid, rhythmic brain-wave activity

Sleep spindles aid memory processing during NREM 2 sleep.

Question 5

brain wave pattern in NREM 3 sleep

Answer 5

Large slow delta waves

NREM 3 is characterized by deep sleep and is hard to awaken from.

Question 6

Where do sleepwalking and sleep talking typically occur?

Answer 6

NREM 3

During NREM 3, the body is internally slow but not externally.

Question 7

brain waves of REM sleep?

Answer 7

Rapid & Saw toothed beta waves

REM sleep involves rapid eye movement and increased heart rate.

Question 8

How long does REM sleep typically last?

Answer 8

10 minutes, gets longer throughout the night

The duration of REM sleep increases as the night progresses.

Question 9

What controls the production of melatonin in sleep regulation?

Answer 9

SCN (Suprachiasmatic Nucleus)

The SCN is the biological/environmental regulator of melatonin.

Question 10

What is the dream theory that suggests dreams help sift, sort, and consolidate experiences?

Answer 10

Information Processing

This theory posits that dreams are related to memory processing and organization.

Question 11

What does the Activation Synthesis theory propose?

Answer 11

Brain’s attempt to synthesize random neural activity

This theory emphasizes the random nature of dreams and neural activation.

Question 12

What is a characteristic of dreams according to Cognitive Development theory?

Answer 12

Reflects dreamers cognitive development

This theory ties dream content to the cognitive maturity of the individual.

Question 13

True or False: Dreams often incorporate negative experiences and feelings of anxiety.

Answer 13

True

- Dreams Help sift, sort, & consolidate experiences in our memory
-

Question 25

Physciological functioning dream theory

Answer 25

**To develop and perserve neural pathways** - Dreams/brain activity provide periodic stimulation

Question 26

Activation synthesis dream theory

Answer 26

**Brians attempt to synthesize random neural activity** -dreams are the brain's attempt to interpret random neural signals generated in the brainstem during REM sleep

Question 27

Cogntiive development theory

Answer 27

**Brain maturation, to stimulate our lives and reflect dreamers cognitive development** - Stimulate our lives; worst-case situations include
